We're kicking off our fourth major leg of our holiday giveaway series, courtesy of NVIDIA's Tegra division. We'll be holding 4 Tegra-themed giveaways over the next four days - so be sure to come back every day through Sunday to check out the latest one. We're starting off by giving away two 3G-enabled Nexus 7 tablets, powered by NVIDIA's Tegra 3 quad-core processor.

What's so special about Tegra 3? Well, for one, you can get exclusive visuals in games like those found in the Tegra Zone. You also get NVIDIA's unique 4-Plus-1 technology, with four processing cores for heavy lifting, and a fifth battery saving core for everyday tasks.

The Nexus 7 3G, as you might have guessed, is a 3G-enabled variant of our favorite Android tablet currently on the market. Packing 32GB of internal storage, HSPA+ connectivity, 7" IPS 1280x800 display, and the aforementioned Tegra 3 processor, it's easily the best tablet value on the market today. We're giving away two Nexus 7 3G's. See below for details.
